Prone positioning during invasive mechanical ventilation improves oxygenation, as shown in large randomized clinical trials of patients with ARDS. In an RCT that included 466 patients with moderate and severe ARDS, prone positioning for at least 16 hours per day with protective mechanical ventilation reduced 90-day mortality. Is prone positioning for respiratory support possible in pregnancy? In this session we will cover the beneficial effect of probe positioning and summarize an article (EPUB) soon to be in print in Obstetrics & Gynecology regarding prone therapy in pregnancy (Tolcher et al).
